If you are in the area and can donate blood to victims who need it, the South Texas Blood and Tissue Center is currently taking appointments, which can be scheduled on their website.

Austin Pets Alive!

Animals that are displaced from the hurricane need shelter and care, and the Austin Pets Alive! center is answering the call.

"Austin Pets Alive! has been helping shelters in the direct line of Hurricane Harvey. We’ve been working with these shelters to transport as many pets as possible to APA! and as of Saturday morning, we’ve transported over 235 animals to our shelter," the organization said in a statement on their website. "Because of the incredible, humbling support we’ve received from the community thus far, we have been able to remove some items from our needs list completely."

Houston Coalition for the Homeless

The Houston Coalition for the Homeless has provided a list of shelters for those in need during the devastation and are also seeking monetary donations to help the influx of people they will are receiving.

“As of this update, Southeast Texas is still experiencing this unprecedented weather event," the Houston Coalition for the Homeless wrote on their website. "Since 2012, local homeless providers have housed more than 11,000 homeless individuals and we are working with partner organizations to see how many of the individuals and families housed in one of The Way Home’s Permanent Housing programs have been displaced from their homes during Hurricane Harvey.

"The Coalition is currently exploring disaster funding that can be used specifically for homeless and displaced formerly homeless individuals to get them back into housing.”
